For people using 3D elevation data with Oziexplorer and oziTarget you may have noticed that the elevation download feature in Oziexplorer is broken. 

Unfortunately this is outside my control as Oziexplorer is not my software.  I have contacted the author of Oziexplorer several times but not had any luck getting him to fix it yet.  Maybe try emailing him yourselves to report the problem.

The failed downloads can also cause crashing issues in Oziexplorer as the zip files it downloads are corrupted and they generate corrupted *.hgt files.

These corrupted files can cause crashes when shutting down and delays while opening maps.

Removing corrupted elevation data

To remove corrupted *.hgt files as follows;

1) Navigate to the elevation data folder  C:\OziExplorer\Elevation Data\Globe\…Country….
2) Delete any files that have a .ZIP file extension or any .HGT files that are under 200kb.  The typical size is around 2mb.

Getting new data

I have found a site that you can manually download the 3 second arc .HGT tiles from an interactive download map here:

1 second arc coverage on this site is not complete but may cover your flying area.  The interactive download map is here:

It is a bit clunky because you need to work out roughly where you are on a world map and then download that bunch of tiles.

Download, unzip and copy to the C:\OziExplorer\Elevation Data\Globe\ directory.  

It seems you can ignore the country folder and just dump them all in together and it still works or create your own sub folders by country, competition or whatever.

Finally make sure that the file path is set in Oziexplorer – 3D/Elevation > Elevation configuration.

Other Data sources

There are other ways to obtain the elevation DEM files such as signing up to the NASA Earth Data site here:

You can then use a nicer interface and the complete 1 Second arc (30m) coverage here: 

Windows protected your PC?  Chrome or Edge won’t let you download oziTarget?

In a world of dangerous software they are just trying to be helpful so read on to see how to get around the road blocks and why they are there.

You’ve bought a registration code and we thank you for your support!  The trick now is to get activated and running oziTarget for real.

There have been a few changes to the registration process so you should find all the answers you need right here.

Yesterday oziTarget was working and now it is not? Wind Lines not drawing or Task Rings not working?

This is a problem caused by partially installed Windows updates or Windows Update waiting for a restart.
